Fujitsu runs a similar farm. For them, one of the advantages was that because they were growing in a disused clean room, formerly a fab, they could control air quality such that bacteria were negligible. This led to produce which could sit on shelves much longer without spoiling. Fujitsu charged a premium since retailers typically lose a portion of their lettuce value to spoilage or discounting. http://www.theregister.co.uk/2014/05/22/fujitsu_grows_lettuce_in_chip_factory/ http://www.theregister.co.uk/2014/05/22/fujitsu_grows_lettuc...
